The models of the world could learn a thing or two from Sheryl Sandberg's Lean In Together campaign. In fact, it seems Tyra Banks already has.

In the wake of Rebecca Romijn and Stephanie Seymour's dis about today's catwalk stars not deserving the supermodel title (and Kendall Jenner's public response), Tyra wrote an open letter on her website to models, past and present, about why they need to unite.

"It's my duty to speak up about the model war going on," she tweeted, posting a link to the essay, "and I've got a lot to say."

She wasn't exaggerating. The part-time sci-fi novelist wrote more than 1200 words in an effort to give some perspective and context to both sides of what she calls the "supermodel wars" between Stephanie and her ilk and the likes of Kendall Jenner and Gigi Hadid.

First, Tyra acknowledged that when she and her peers were coming up in the early '90s, they had little in the way of technology to advance their cause -- or even help them find their way around cities like Paris and Rome.

"... After all that hard work, dedication, sacrifice, sidewalk pounding, map folding, metro riding, model apartment living… after all the blood, sweat, fears and floods of tears… we finally were bestowed with the coveted title of Supermodel!" she wrote. "Fast forward to present day, and some of us are in a state of shock. We witness young girls on reality shows and super popular girls on social media now being called Supermodels and think, 'WHAT?! It's not fair! Is that kind of success even real?' I've gotta be blunt," she continued. "Yes. IT IS REAL."

From there, she explained the new kinds of pressures today's supermodels face -- from social media pressure to remain interesting, on and off the catwalk to what it must be like to feel like "the world is watching your every move, judging whether or not you have acceptable personal style."

Giving both sides of the issue equal love and consideration, she then made a plea that echoes much of what the new arm of the "Lean In" campaign is all about.

"Yesterday's 'Trinity' is today's #Squad. And what we all must remember is that we are stronger together than apart," Tyra declared. "I hope we can start to act like it. I've had enough pain from my modeling years in the past and seeing my sisters in conflict today brings back those gut-wrenching memories. So, let's band together and unite. Please end the fight."

In the end, she noted, "The modeling world is now a democracy and we need to celebrate it, lean into it," adding, "The universe constantly changes and evolves, and will continue to do so until the end of time. It's inevitable. And it's beautiful. … Just like all of you reading this right now."
